I'd like testing some cross-compile qt5 applications, in the past I was able to use wine for testing. However, recently this does not work anymore, the application runs on windows but crashes on wine (if you want, I can send details ). I suspect that recent versions of qt5 require opengl 1.3. Therefore, I'm trying to compile wine (actually wow64) from source with opengl 1.3 support, and was trying to follow the documentation [1,2]. I'm testing on debian 10 and did
I doubt it has anything to do with OpenGL 1.3. GL 1.3 is ancient, Wine supports way newer GL versions. I suspect that either your host OpenGL is broken (e.g. there are libs to link against but loading the mesa driver or creating a context fails) or your program is not working for some other reason.
Afaik Qt internally uses GL:ES, which is provided by ANGLE, which wraps to d3d11, which we then wrap to whatever OpenGL is available. I might be wrong on that though and confuse it with other components that use ANGLE.
Hello,
I don't know about Qt but I know this bug related to ANGLE:
https://bugs.winehq.org/show_bug.cgi?id=44985 Many applications using CEFv3 Angle OpenGL ES 2.0 for H/W Accelerated Canvas and WebGL display blank/black windows (disabling or removing 'libglesv2.dll' is a workaround)
